Title: Improvements in and relating to a process for making plywood
IPC: B27D1/04
Filed: 1933-06-14
Abstract: 425,600. Ply-wood sheets; veneers. PIORNIK, H., 7, Ulica Ceglana, Warsaw. June 14, 1933, Nos. 17011, 17012, 17013, 17014, and 17015. Convention dates, June 14, 1932, June 27, 1932, April 22, 1933, Jan. 13, 1933, and Aug. 5, 1932. [Class 145 (ii)] [See also Group VIII] Plywood is made, entirely or in part, from veneers or boards from which the resins have been leached out e.g. by means of boiling water or aqueous solutions of alkali or alkaline earth hydroxides, sodium or potassium carbonate, borax, waterglass, sodium phosphate, soap, sulphonated organic compounds such as turkey red oil, &c., singly or in combination. Alternatively the wood blocks from which the veneers are cut may be deresinified. The veneers may be washed or rinsed, and glued wet or dry. The plywood may comprise different woods, e.g. deresinified pine or fir veneers may be layered with ash, oak, birch, alderwood, &c. Specification 18010/99, [Class 145], is referred to. The Specification as open to inspection under Sect. 91 describes also compound sheets consisting of deresinified veneers &c., and metal foils or sheets. This subject-matter does not appear in the Specification as accepted.

Title: A switching device for firing automatic firearms
IPC: F41A19/64
Filed: 1961-05-10
Abstract: 968,344. Automatic firearms. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. May 10, 1961 [May 11, 1960], No. 17016/61. Heading F3C. Relates to a switching device for an electrically operated firing mechanism for automatic firearms, in which a firing linkage is operated by a spring-urged electromagnet moved against the action of its spring on energization thereof, means being provided for effecting continuous fire or single round firing. For continuous fire, a selector switch r is closed and a switch a actuated so that an operating relay t receives voltage via switch r and closes a switch t 1  in the operating circuit so that the magnet g is energized and moves to the right to affect firing. The magnet g is coupled mechanically with an auxiliary switch p which is then moved from position 1 to position 2. An auxiliary relay s has a normally closed contact s1 and normally open contact s2 and now receives voltage via the switch p and remains self-holding via contact s2 so long as the switch a is closed. On opening switch a, the relays t and s are de-energized, the magnet is released and continuous fire terminated. For single rounds, the selector switch r is opened and on closing switch a, the operating relay t receives voltage via the switch p and contact s1 so that the switch t1 closes, the magnet g moves to the right moving the switch p to position 2. The coil of relay t is thus deenergized and simultaneously the relay s receives voltage and becomes self-holding by means of the closing of contact s2. Since the relay t has been de-energized, the switch t1 opens and the magnet g is restored to its normal position, a single round having been fired. Since the relay s is still energized through contact s2, the contact s1 is open and the operating relay t cannot operate again even when the switch p has returned to position 1, until the auxiliary relay s releases as a result of opening switch a and the contact s1 closes again. Only then can another single round be fired by the closing of the switch a. Fig. 1 (not shown) is said to show a known switching device.

[Class 98 (ii)] Separate colour records are obtained, from latent image records, made in two emulsion layers directly and inseparably superimposed on one side of a support, by developing but not fixing the layers, converting the unreduced halide in both layers to a light insensitive form, e.g. silver iodide, photographing the image next to the support and reversing or printing the photograph to yield the first separate colour record, and then so processing the layers as to eliminate this image, leaving the remaining image as the second separate colour record. This processing may consist in fixing both layers, bleaching both silver images, redeveloping the upper image only with a loaded developer, and then fixing out the lower image. The two-layer material may be one element of a bipack for tricolour work.
